If I recall correctly, some of the parts that looked largely the same were hard plastic in the Celica vs. padded vinyl in the Supra. Been so long since I've seen a Celica, can't remember tho. I'll try to find time this weekend to check if I've got a mirror. I've got a few in remote storage but don't remember what years they are from or which sides. Its he!! getting old.The Celica interiors are mostly different, but look similar. I mean it will mostly bolt up at some level since the Sheetmetal is largely the same behind the firewall. Look at the Euro Mk2 that have mostly a Celica interior in them. The dash for instance is completely different, same with the center console, side panel, the trunk, etc.
